SPRING ATTACHMENT FOR SUSPENDERS, 81.0.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed February 28, 1906. Serial No. 303,462.

To all whom it may concern.-

Be it known that I, PAUL E. Wm'r, a citizen of the United States, residing at Bloomsburg, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Spring Attachments for Suspenders, &c., of which the following is a specification.

This invention relates to spring attachments or resilient connections of the type designed to be employed as a substitute for the elastic medium usually embodied in wearing ap arel and analogous articles.

n carrying out the above general object, the invention has in view the provision of a spring attachment or resilient connection possessing special utility as a connection for suspender ends, while at the same time of such a construction as to be capable of practical use for other pur oses where it is desirable to employ a res] ient connection providing a free and lively spring action, while at the same time permitting of selfadjust ment to various positions under stress exerted at different angles. Also, the invention contemplates, in a spring attachment or resilient connection of these qualities, one which shall also possess great durability and strength so as to insure reliability in service and action.

To this end the invention specially contemplates a practical improvement in the type of spring attachment or resilient connections disclosed in my series of former patents Nos. 692,041, 692,042, and 692,096, dated January 28, 1902.

A further object of the invention is to improve the retaining means for the fast end of the attaching elements, and also to provide improved means for connecting the spring attachment with a suspender end to permit of perfect freedom of movement in any and all directions.

The essential features of the invention may be structurally changed without departing from the scope thereof, but a preferred embodiment of the improvement contemplated herein is shown-in the accompanying drawings, in which,

Figure 1 is a perspective view of a spring attachment constructed in accordance with the present invention and shown applied to the front end of a non-elastic suspender strap. Fig. 2 is a similar view showing more plainly the manner of loosely hanging the duplex spring-coil member upon the fastener stud of the cast-otl', and exposing the spiral duplex spring-coil member. Fig. 3 is an elevation, partly in section, showing the improved spring attachment applied to the rear or back end of a pair of suspenders. Fig. 4 is a plan view of the duplex spring-coil member showing the separate spiral coils pulled open or distorted for the purpose of disclosing more clearly the formation of the separate coils from a common core or center coil. Fig. 5 is a cross sectional view of the duplex coil in its normally closed condition showing the pair of separate flat spiral coils arranged side by side in arallel relation and spirally formed from t 1e core or center outward. Figs. 6 and 7 are details in perspective of the fast end of an attaching element or cord illustrating the referred way of forming the retaining hea or button thereon.

Like references designate corresponding arts in the several figures of the drawings.

The leading and distinctive feature of the present invention resides in the construction of the spring wire body, designated, in the drawings, in its entirety, by the numeral 1. This spring wire body preferably consists of a single length of spring wire of suitable strength and weight, and in shaping the same to a form adapted for the purposes in tended, the wire length or strand is provided at a oint between its ends with a plurality of spirally arranged spiral convolutions forming what may be properly characterized as a duplex spring-coil member 2 which is ollset laterally from the main length of the wire strand and is intended to increase the resiliency of the wire body, and at the same time serves to cause said body to entirely resume its original set when being completely relieved of stress or strain.

It is important to note in connection with the centrally located, and laterally offset, spring-coil member 2, that the latter embodies a pair of flat spiral spring-coils 3 arranged side by side in a normally parallel relation and having a common core or center coil 4. This construction of spring-coil is plainly shown in detail, in Figs. 1 and 5 of the drawings, and it will be observed that the spiral convolutions of the separate springcoils 3 wind respectively in reverse or opposite directions to those of the companion coil, while at the same time, inboth of the flat spiral coils, it will be noted that the same are formed spirally from the core or center outward. This is important from a mechanical standpoint, inasmuch as such construction divides'the tension or stress from the middle outward, so that in bending, the outer convolutions'being the larger or longer ones, take most of the stress and reduce the possibility of breakage to a minimum. Furthermore, this construction of duplex spring-coil gives perfectly reliable results, whereas other forms of springs heretofore constructed for similar purposes could not be so thoroughly relied upon, as it is ordinarily impossible to tell the perfect from the imperfect springs on account of the spring wire being uncertain in temper and tensity in places. These difficulties are obviated where the duplex spiral spring-coil member is made by separate flat spiral spring-coils arranged in registering parallel planes, side by side. It should be further observed in connection with the construction of duplex coil claimed herein, that inasmuch as the center convolutions are usually comparatively short and rigid, the stress or strain is necessarily graduated owing to the formation of the spring from the center outward, thereby insuring great flexibility and durability, and besides the possibility of breakage is reduced to the lowest possible minimum. h

In addition to the central duplex spiral spring-coil member 2, the spring wire body 1 is provided with oppositely extending yielding side arms 5 constituting continuations or extensions of the outermost convolutions or coils of each ofthe separate spiral springcoils 3. The said opposite side arms 5 are preferably straight and disposed in their normal positions at approximately right angles to the transverse plane of the laterally ofl'set duplex coil member 2. These side arms are designed to carry at their terminals antifriction guides 6 of some suitable form. These guides serve to loosely and freely carry the flexible attaching element or elements 7 which afford a connection between the spring wire body and the pantaloons or other object to be yieldingly held fastened or supported.

In the embodiment of the invention illustrated in the drawings, separate attaching elements 7 are employed, and the same are illustrated as oppositely reeved, but arranged in parallel relation to each other and to the yielding side arms 5 between the oppositely located anti-friction guides 6. Each separate attaching element or cord 7 has a fast connection at one end with a holding collar or element 8 conveniently carried by and forming a member of one of the anti-friction uides 6, and loosely running through the fiaredrmouthed sleeve 9 of the anti-friction guide 6 at the terminal of the opposite arm 5. .This provides means whereby a uniform direct pull or stress may be exerted upon the terminals of both of the side arms of the spring wire body.

In carrying out the invention, it is desirable to provide that portion of the attaching element or cord 7, running through the guiding sleeve 9, with a coating or application 10 of paraffin or other suitable lubricant to prevent abrasion or wearing out of the cord as it moves backward and forward through the eye. This part of the invention may be carried out by applying hot parafiin to the cord or attaching element thereby saturating the cord or element with the lubricant to such an extent that it is not appreciably noticeable, while at the same time securing the lubricating functions desired.

Each of the attaching elements or cords 7 is provided at one end with the usual tab or loop 11 for connection with the article of wear, and the present invention contemplates an improvement in the means for mak ing the fast or retaining connection between one end of each attaching element and the stress point 8 for the spring arm. Without employing metal parts for effecting this connection, it is proposed by this invention to first fray an end of the attaching element as indicated by the numeral 12 in Fig. 6 of the drawings, and then apply to such frayed end enamel, or a suitable cement. This material will thoroughly saturate the frayed end 12, and when the latter is partially dry, the same is compressed to form a hard retaining head or button 13 preferably of shouldered forma tion which will be securely held in the collar or element 8 to form positive securing means preventing the element or cord from pulling out.

In the application of the invention, it is preferable to employ the same in a way to prevent wear upon the clothing, especially when used with the form of suspenders illustrated in the drawings. For instance, as shown in Fig. 1 of the drawings, the number 14 designates the front end portion of an ordinary suspender strap having fitted thereto a looped cast-off 15, the separate members of which are separably connected by a fastener 16 which includes a headed stud 17 over which the spring-coil member 2 is loosely hung. I/Vhen thus applied, the spring body has perfect freedom of movement while at the same time being housed within the castoff 15. Also, in the arrangement shown in the drawings, in Fig. 3 the numeral 14 designates the back of a pair of suspenders, to the end of which is connected a 100 ed suspender end 18, the side portions of w ich are connected by a supporting rivet 19 over which is hung the coil member 2, thereby providing for the pivotal support of such coil member while at the same time serving to completely house the same.

From the foregoing it is thought that the construction and many advantages of the herein described spring attachment, will be readily apparent Without further description, and it will be understood that changes in the form, proportion and minor details of description may be resorted towithout departing from the spirit or sacrificing any of the advantages of the invention.

I claim:

1. A spring attachment of the class described, comprising a spring wire body provided with a pair of parallel springcoils arranged side by side and having a common core or center coil, said spring wire body carrying attaching elements.

2. A spring attachment of the class described, comprising a spring wire body carrying attaching elements and provided with a plurality of parallel spiral spring-coils having a common center coil and the convolutions of both of which coils are formed outwardly from said center coil.
